To all whom it may concern:

Be it known that I, BIRNEY C. BATOHEL- LER, a citizen of the United States of America, a resident of Brookl n, in the county of Kings, State of New ork, have invented certain new and useful Improvements in Bag-Turnin 'Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in bag-turning machines, one 1 of the objects being to provide an eflicient means for holding the bags during the turning'operations. As an illustration of this feature of the invention, I will hereafter describe a pair of bag-holding arms adapted to enter the mouth of a bag and yielding means whereby one of said arms is forced away from the other to frictionally secure the bag, the latter being stripped from said armsduring the bag-turning operation. To receive the bag, one of the bag-holding arms moves to-- ward the other and both arms preferably move away from the path of a bag-turning member. The mouthof the bag is slipped over these arms and a spring forces one arm away from the other to open the mouth of the bag and frictionally engage the arms with the bag. The bag itself limits the motion of the spring-actuated arm, and this compensates for variations in the dimensions of the bags and insures the desired frictional engagement between the bag-holding arms and the bag.

Another object is to produce a simple and effective bag-turning device adapted to enter and turn the bag held by a bag-holder.

This feature is illustrated by a'pair of bag turning members in the form of curved rods movable about different axes, so as to enter. the mouth of the bag and move in lines diverging from the mouth to the corners at the closed end of the bag. The axes of these curved rods lie at an angle to each other, and the parts are so arranged that the bagengagingends of the rods enter the mouth of the bag and move in diverging lines until they engage opposite sides of the bag. Thereupon, the ends of the rods slide along the bag and effectively turn the corners at the closed end thereof. The bag-turning rods are preferably yieldable, so their ends will frictionally engage opposite sides of the bag while the operating means is tending to move said ends in diverging paths.

A further object is to produce a bag-turning machine that can be easily and quickly ad usted to receive bags of different widths. The various bag-holding and turning elements are arranged in pairs at opposite sides of the machine, and the elements at one side are mounted on a support which can be adjusted toward and away from the other side of the machine. More specifically stated, the machine includes a pair of supports each provided with a bag-turning member, a bag-holding member and other mechanism for operating on only one side of the bag. and the supportsare adjustable toward and away from each'other to vary the distances between the companion members at opposite sides of the machine. By merely moving these supports, the entire machine can be properly adjusted for bags of different widths.

With the foregoing and other objects in view, the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawcome within the scope of the claims hereunto appended.

1 desi ates a table (Fig. I) upon which a pile bags A is supported. An operator removes the bags, one at a time, from the table and places them on a bag-holder having arms 2 and 3 adapted to lie in the mouth of the bag to be turned. Bag-turnin members 4, preferably in the form 0 long, curved rods, or stlcks, are movable in armate paths, as suggested by dotted lines in Fig. I, to turn the ba s, stripping them from the bag-holder and forcing their closed ends between the ripping jaws 6 and 7, as will be hereafter escribed. The bag-holder comprises a pair of oscillator supportin members 8 (Figs. I, III and mounted on pivots 9 and movable from the position shown by full lines in Fig. I to the position shown by dotted lines. Each oscillatory supporting member 8 is provided with a non-rotary rod 10 to which a bag-holding arm 3 is secured, and 'an oscillatory shaft 11 to which a bag-holdin arm 2 is secured. The arm 3 is not mova 1e about the axis of rod 10, but the shaft 11 can be turned to move the arm 2 toward said arm 3, as indicated by dotted lines in Fig. I.

Each oscillatory supportingmember 8 is provided with operatin means including an oscillatory shaft 12 igs. I, II and III) to which a crank arm 13 is secured, and a connecting rod 14 connecting said crank arm to the member 8. Each shaft 12 is provided with a pinion 15 II) meshing with a rack bar 16 (Figs. I, I and III), said rack bar being pivoted to a rotary crank 17 on a shaft 18. The rack bar and pinion are enclosed by a housin 19 pivotally mounted on shaft 12 and aving a tubular portion whereby the rack bar 16 is guided and retained in mesh with the pinion 15. Through the medium of the mechanism just described, each oscillatory supporting member 8 is shifted from the a -receiving position shown by dotted lines in Fig. I to the bag-turning position shown by full lines. When the oscillatory supporting members 8 move to the position indicated by dotted lines, the arms 2 move toward their companion arms 3, as will be hereafter described, so the bags can be readily slipped onto the arms 2 and 3 While the companion arms are located adjacent to each other at points entirely beyond the paths of the bagturning members 4.

The means for moving the bag-holding arms 2toward and away from the arms 3 includes two sets of mechanisms, one set for each pair of arms 2 and 3, as shown by Figs.

I, III and VII. Each of these sets comprises an operating arm 20 rigidly secured to shaft 11, a connecting rod 21 having its up per end pivoted to arm 20 and its lower end pivoted at 22 to a lever 23, the latter being fulcrumed at 24 and connected to'the lower end of a rod 25 having its upper end pivoted to an arm 26 which is pivoted at 27 (Fig. VII) and provided with a roller 28 adapted to be engaged by a rotary cam 29 fixed to the necting rod 21 under tension, so as to trans-- mit power through the operating arm 20 to the bag-holding arm 2, thereby yieldingly forcing arm 2 away from arm 3. These arms lie in the bag A, and the motion of arm 2 is limited by the bag itself, and not by the cam 29 and roller 28. This compensates for variations in dimensions of the bags and insures the desired frictional engagement between the bag-holding arms 2 and 3 and the inner face of the bag. While a bag is frictionally held in this manner, the bagturning rods 4 move downwardly to turn the bag, as will be hereafter described, the bag being eventually stripped from the arms 2 and 3.

When the supporting members from the position shown by full lines in Figs. I and VII to the position shown by dotted lines in Fig. I, each cam 29 (Figs. III and VII) en ages a roller 28 on an arm 8 move 26, with the resu t of depressing vertical rod 25 and transmitting motion through lever 23, rod 21 and arm 20 to bag-holding arm 2, thereby moving said arm 2 toward the arm 3. As the cam 29 continues in motion, the arm 2 is held adjacent to the arm 3 so as to give the operator an opportunity to slip a bag over the adjacent arms, and the cam is eventuall separated from roller 28, as sug' gested in Fig. VII, to permit spring 30 to act upon arm 2, as previously pointed out. The cam 29 forces arm 2 toward arm 3, and the spring 30 is utilized to yieldingly move arm 2 away from arm 3. 4

The mechanism just described is supported partly by the stationary frame of the machine and partly by the oscillatory supporting members 8 which carry the arms 2 and 3. Each oscillatory member 8 is constantly in motion, and such motion should not materially affect the means for oscillating arm 2 about the axis of its shaft 11. Each arm 2 is therefore acted upon by a set of mechanism having a pivotal connection 22 (Fig. VII) located near and in approximate alinement with the pivot 9 (Fig. I). which supports the member 8. As a consequence, when a member 8 swings about the axis of its pivotal support, the rod 21 (Fig. VII) moves about the axis of its pivotal connection 22, so the oscillatory motion of the member 8 does not materially displace the mechanism for transmitting motion to arm 2.

The curved bag-turning rods 4 have their upper ends secured in soc ets 31 at the upper ends of rigid operating arms 32. Each socket 31 (Fig. VII) is pivoted at 33 to the upper end of an arm 32, and the socket can be adjusted about the axis of the pivot to properly locate its rod 4. After a socket ha been adjusted, it is secured by means of screws 34 passing through slots 35 in arm 32 (Fig. VII) and screwed into the socket, said screws havingheads adapted to frictionally en age the arm 32 so as to secure the socket. Each arm 32 is rigidly secured to a short shaft 36 mounted in a bearing 37, as shown by Figs. I, III and IV. The axes of shafts 36 lie at an angle to each other, (Fig. IV), and each bag-turning rod 4 is preferably concentric with the axis of its shaft 36. However, since the shafts 36 lie at an angle to each other, it will be apparent that the rods 4 do not travel in parallel paths. These curved rods are preferably made of elastic metal, and their bag-engaging lower ends advance in true arcuate lines diverging from the mouth of the bag to the sides of the bag. When the bag-turning rods occupIy their elevated positions (Figs. I and II), their lower ends lie adjacent to each other. As the rods move downwardly about the axes of shafts 36, they pass through the mouth of the bag A held by arms-2 and 3, and at the same time the bag-engaging ends of these arms move away from each other, so as to engage the sides of the bag. The bag-engaging ends are thus freely inserted into the bag and moved away from each other to frictionally engage the opposite sides of the bags. The elastic rods will then yield, for they cannot move away from each other after they have been forced into firm engagement with the sides of the bag, and the ends of said rods will finally engage the corners at the closed ends of the bag, so as to positively turn the corners. T hereupon, the bag is gradually stripped from the bagholding arms 2 and 3, and its closed end is forced into a gripping device, aswill be presently described.

The means for oscillating the bag-turning rods 4 comprises a pair of cranks 38 (Figs.

1- I, III and VII), and connecting rods 39 extending from said cranks to the arms 32. The shafts 18 are parallel with each other, and the crank arms 38 move about the axis of these shafts, while the long arms 32 move about the axes of shafts 36 which lie at an angle to each other. Therefore, the ends of the connecting rods 39 are flexibly secured ping devices are arranged about the axis of a shaft 41. The means for supporting the gripping devices includes a pair of sleeves 42 igs. I and .V) slidably mounted ona non-circular portion of the shaft 41 and provided with flanges 43 and 44. These sleeves 42 can be adjusted longitudinally of the shaft 41, as will be hereafter described. Each sleeve 42 is provided with a series of the gripping jaws 6 and 7, and I will now describe the elements associated with one sleeve 42, it being understood that the other sleeve is provided with the same elements. 45 desi ates circular frame members (Figs. I and in the form of angle bars concentric with shaft 41 and rigidly secured to a flange 43 by means of bars 6 to which the gripping jaws 6 are rigidly secured. Each bar 6' may be riveted to a flange 43 on a sleeve 42, and also riveted to a circular frame member 45. As shown by Fig. V, each gripping jaw 6 .may be riveted to a pair of the bars 6. Each gripping jaw 6 is thus rigidly secured to its supporting frame.

Each gripping jaw '7 is formed on the outer end of an arm 7 having its innerv end pivoted to a sleeve 42, as shown by Figs. I and V. 46 designates bell crank levers (Figs. I and V) pivoted to the rigid bars 6', each of said levers having a long arm provided with a roller engaging one of the arms 7 and a short arm to which a tension spring 47 is secured. Each spring 47 cooperates with a bell crank lever 46 to force one of the gripping jaws'7 toward its companion gripping jaw 6. Immediately before a bag is forced into a gripping device, the jaw 7 is moved away from the jaw 6 to provide a space for theincoming bag, and as will be hereafter described, the jaw 7 is afterwards released and restored by its spring 47 and bell crank lever 46, so as to grip the bag. The bag-turning rods 4 are then withdrawn from the ba while the latter is held by the grippers. fter a number of bags have accumulated in one of the gripping devices, all of the gripping devices can be moved about the axis of the shaft 41 to displace the collection of bags from the paths of the bag-turning rods and to locate an empty gripping device at said paths.

Each gripping device includes two upper gripping jaws 6 (Fig. V) adapted to lie above the corners of the bags A, and a pair of ripping jaws 7 located below said jaws 6. The means for opening the gripping device includes a air of rotar shafts 48 (Figs. I, V and I) having t eir axes at opposite sides of the gripping device. Each shaft 48 is provided with a pair of arms 49 and pressure fingers 50 extending from said arms. Each pressure finger 50 moves in a circular path about the axis of the shaft 48 to which it is secured, and the collection of bags in th gripping device lies in the paths of the pressure fingers To open the gripping device, pressure fingers 50 press upon the top bag in the collection, with the result of forcing the collection of bags downwardly, thereby moving the yieldable gripping jaws 7 downwardl relative to the rigid gripping jaws 6. uring this operation, the pressure fingers 50 cooperate with the yieldable gripping jaws to prevent displacement of th collection of bags. A bag can then be inserted into the gripping device, and after this has been done the pressure fingers pass away from the bags to release the yieldable gripping jaws 7, which are restored through the medium of springs 47. The shafts 48 are rotated in opposite directions, and the pressure fingers 50 move downwardly across th path of the bags passing to the gripping device. As shown by Fig. V, the rigid gripping jaws 6 are provided with notches to receive the ends of the pressure fingers 50. Each finger 50 lies at an angle to the axis of its shaft 48, and each gripping jaw 7 has an inclined outer edge conforming to that angle, as shown most clearly by Fig. V.

The means for rotating the shafts 48 ineludes bevel gears 51 shown by Figs. I and V. Each bevel gear 51 meshes with a smaller bevel gear 52 fixed to the lower end of an inclined shaft 53 (Figs. I and III) the upper end of said shaft being provided with a gear 54 meshing with a gear 55 on one of the rotary shafts 18. Owing to the speed reduction at the gears 51 and 52 (Fig. I), each shaft 48 turns only one-half of a revo' lution during each operation of the machine, but each shaft 48 is provided with two pressure fingers 50 so the gripping device is opened in response to each operation of the machine.

The short shafts 18 transmit motion to various mechanisms that have already been described, and each of these shafts is provided with a large driving gear 56 meshing with a pinion 57 on the main power shaft 59.

I will now point out the manner in which the machine can be adjusted to receive bags of different widths. The means for supporting the various moving parts includes a stationary, or non-adjustable, main supporting frame, and a pair of adjustable supporting frames movably mounted On the main frame and adjustable toward and away from each other. The adjustable frames lie at opposite sides of the machine, and each of these frames carries approximately one-half of the mechanism. The main supporting frame comprises side frame members B rigidly connected together bfi means of an upper connecting member (Figs. I, III, IV and VII) and a lower connectin member B, the latter being shown in Fig. %II. It is to be understood that these members B, B and B are rigidly secured together to form a stationary, or non-adjustable, main frame. There are two adjustable supporting frames, each com risin an up er frame member C (Figs. I, II, I and II), an arm C extending rearwardly from said u per frame member, and a leg C extending ownwardly and forwardly from said upper frame member. As shown by Figs. I and VII, the arm C is rigidly secured to the upper frame member C by means of bolts 60, and the leg (3 is rigidly secured to said u per frame member by means of bolts 61. Fach upper frame member C is slidably mounted on the stationary, or non-adjustable. frame member B (Figs. I, III, IV and VII), the latter being horizontal and provided with longitudinal shoulders to receive guide bars 62 (Figs. I and VII) carried by and secured to the upper frame member C It will now be understood that each adjustable frame, including frame members C, C and C is slidably supported by the horizontal stationary frame member B, and that the adjustable frames can be moved toward and away from each other.

The means for moving the adjustable frames comprises a long, horizontal screw D (Figs. I, III and VII), rotatably mounted in bearings 63 on the stationary side frame members B, and having a right-hand thread 64 (Fig. III) and aloft-hand thread 65. The arm C forming part of one of the adjustable frames is provided with a nut 66 (Fig. III) to receive the right-hand thread, and the arm C of the other adjustable frame" carries a nut 66' to receive the left-hand thread. The screw D has a. non-circular end ,67 (Fig. III) to receive a tool whereby the screw can be turned in opposite directions to move the adjustable frames toward and away from each other. The bag-holding elements and bag-turning elements are arranged in pairs on the adjustable supports so as to lie at opposite sides of the bags where they cooperate with each other to support, turn and feed the bags. Each adjustable supporting frame comprising members C, C? and C carries one of the oscillatory arms 8 provided with a pair of bagholding members 2 and 3, as well as a bearing 37 for an arm 32 to which a bag-turning rod 4 is secured, and in addition to this each adjustable frame carries operating mechanism for'the elements just referred to. Each I assess? adjustable frame also carries one of the shafts 48 provided with a pair of fingers 50 to en a gripping device 6-7 at one side of the machineyandeach of these frames supports the mechanism for transmitting motion to its fin ers 50.

More specificall stated, each ad'ustable I frame is provide with a rotary s aft 18 (Figs. I and III) which,as heretofore pointed out, transmits motion to one of the bagturning rods 4. Each shaft 18 is rovlded withv a large gear.56"(Figs. I and-VI )mesh- 'ing'with a pinion 57 on the main '0 erating shaft 59. This main shaft is not admstable, but the pinion 57 is keyed to said shaft so" the-pinion can be adjusted longitudinally of the shaft to remain in mesh with the gear 56.

2 I will now point out the means 'for moving the gripping devices toward and away from each other in response to corresponding movements of, the ad'ustable frames. As shown by Figs. I and each set ofgrippmg devices is carried by a sleeve 42 slidabliy mounted on a non-circular portion of she 41, the latter being rotatably mounted in stationary bearings 68. Fig. V shows that each sleeve 42 is provided with an annular recess adapted to receive the rear end of one of the arms C. When the adjustable frames are moved toward or away from each other, the arms C cooperate with sleeves 42 to impart a corresponding movement to the pairs of gripping elements. These elements serve as means for stripping the bags from the bag-turning rods 4, and it will be apparent that they are adjusted with the other elements of the means for turning and feeding the bags.
